Emmys: Amy Schumer Reveals How She and Jennifer Lawrence Ended Up Dancing on Billy Joel's Piano

"I've been a groupie for years, just touring with him, riding in the van, putting out," Schumer joked before revealing the real story.

Amy Schumer was an early guest on E!'s pre-Emmys red-carpet special, stopping to talk with co-host Ryan Seacrest. The four-time Emmy nominee brought her sister, Kim, up on the podium with her as she danced and did a bit of singing. But talk quickly turned to another memorable Schumer dance, when she and pal Jennifer Lawrence danced barefoot on the piano at a recent Billy Joel concert, with video footage of the incident quickly popping up online.

After Seacrest played the clip, Schumer explained how the moment came about.

"I've been a groupie for years, just touring with him, riding in the van, putting out," she quipped before beginning the real story.

Schumer explained that one of her best friends from her Inside Amy Schumer show loves Billy Joel and noted that Joel's music was a big part of her hit summer movie, Trainwreck. Schumer said that she told Joel that she and her friends would be in Chicago and he invited her to come up on the stage and sing "Uptown Girl," which plays a recurring role in Trainwreck.

She revealed it wasn't her idea to get up on the piano.

"I'm not trying to get to higher surfaces. I like things on the ground. I weigh a buck fifty. Let's keep me low," Schumer said.
